We describe an abstract methodology for exploring and categorizing the space of
error traces for a system using a procedure based on Satisfiability Modulo
Theories and Bounded Model Checking. A key component required by the technique
is a way to generalize an error trace into a category of error traces. We describe
tools and techniques to support a human expert in this generalization task.
Finally, we report on a case study in which the methodology is applied to a
simple version of the Traffic Air and Collision Avoidance System.
